Well common sense never does apply to most bureaucracies. Or prisons. If you are in a UK prison, they won't let you wear say a pair of Army boots cos the toecaps are reinforced, but if the prison you are in has you doing almost ANY type of manual work you will be issued with steel toecapped safety boots which you are meant to wear back to your cell.
Or you can find a D Cat (open ) prison like HMP Leyhill where if you are in the music group you are not allowed access to a screwdriver and a spanner or pair of pliers under supervision of the outside music teacher to tighten the nuts on an amp or a strat copy ( for security reasons) but if you are in farms and gardens. you will be wandering around with an AXE on your shoulder and no-one bats an eyelid.
